1) Move the decimal until your number appears to be between 1 and 10 count the spaces that you move the decimal.
2) use the number of spaces as the exponent of 10 (the base)
3) if the original number was greater than 10, the exponent is positive, if the original number was less than 1 then the exponent is negative.
EX: 250,000 becomes 2.5 x 105
but 0.0025 becomes 2.5 x 10-3
In scientific notation all numbers are written in the form: a*10b where a is a decimal number such that 1 ≤ a < 10 and b is an integer.
I don't know what you mean "how to write the rules." In the US, "standard" notation means "long form", i.e. 6,000,000, while "scientific" notation means the exponential form, 6x106. I had thought it was the same in the UK, but Mehtamatics says otherwise: "Standard notation and scientific notation are the same in terms of UK usage of these phrases."
standard notation and scientific notation For example: 126,000 is standard notation. 1.26X105 is scientific notation.
Scientific Notation, Standard Form and Exponential Notation are used in different countries but all have the same meaning. It is a way of expressing a number as a value between 1 and 10 multiplied by a power of 10. 5.63 x 10² is the standard form number of 563. 8.6927 x 10^4 is the standard form number of 86927.
Scientific notation is a special way of writing larger numbers that can be easily handled by scientists.

20,000 + 3,400,000
Scientific notation is a convenient tool for writing very large or very small numbers.

4,000,000 in Scientific Notation = 4 x 106
Standard notation (in the UK) is the same as scientific notation. So the one rule to use is DO NOTHING!
Scientific notation is a way to signify really long numbers without writing it out in full, all 50 digits. 1,000,000,000 in scientific notation is 1.00 X 109
64 can be written as 6.40 × 101 in scientific notation.
